Title: Group keys for rotary cylinder locks in locking systems
IPC: E05B27/00
Filed: 1976-11-17
Abstract: In this flat group key, the blocking grooves and blocking ribs (a-i) are respectively provided severally next to one another in a cascade-like manner in the flanks of variation grooves (3, 4) which are located in the region (10) of the key free of key indentations. The variation grooves (3, 4) and the remaining grooves (5, 6) located in the key-indentation region (7) extend respectively beyond the longitudinal mid-plane (11) of the flat key and therefore overlap to a corresponding extent. In such flat group keys, this achieves an even greater possibility of variation in terms of their diverse basic profiles, and the basic profiles cannot be falsified by the key indentations. At the same time, the safety of the associated rotary-cylinder locks against unauthorised unlocking is also increased. <IMAGE>

Abstract: 1288029 Semi-conductor devices TOKYO SHIBAURA ELECTRIC CO Ltd 9 Oct 1970 [7 Feb 1970 2 March 1970 13 March 1970 28 March 1970] 48163/70 Heading H1K A surface region of a silicon body is simultaneously diffused with arsenic and phosphorus or boron. At the surface of the region the ratio of the number of atoms of phosphorus or boron to that of arsenic is 100 : 3-40. The presence of arsenic reduces the number of lattice defects and precipitates formed in the region particularly if the semi-conductor substrate includes less than 1000 dislocations/c.c. and/or has its surface orientated in a 111 crystallographic plane. In described examples the arsenic and boron or phosphorus are diffused in simultaneously as from a suitably doped silicon oxide layer formed by oxidation of silane, and overlying an aperture in a silica mask. Such a process may be used to form a diode from an N-type Si body. To form a PNP transistor a P-type layer is first epitaxially grown on a P + substrate, phosphorus and arsenic doped silica deposited and then apertured at the emitter site and a second layer of boron and arsenic doped oxide deposited overall. The resulting wafer is then heated to cause diffusion. Methods of forming a P + NN + diode, a controlled rectifier, and a planar NPN transistor are also described, the last-mentioned involving diffusion from boron nitride to form the base zone followed by an emitter diffusion of phosphorus and arsenic as described above, which causes no appreciable "emitter dip".

In the mounting of transparencies or like film, a film roll 1 is laterally guided and advanced in a block unit 3 to be cut into single views 180 by a knife, such as 20, the cut views 180 are transferred singly by a pivotal arm 42 to between the hinged together shutters 158 of a mount 122 treated with adhesive, the shutters 158 are closed to contain a view 180 and the closed mount 122 is advanced between motor-driven presser rollers 140, 142 to bond together the shutters 158 prior to discharge into a collecting channel 160. The block unit 3 is positionally adjustable to accommodate differing film sizes. A 35mm. film 1 having edge perforations 12 is advanced by a pawl 10 pivotally and adjustably carried on the ram 6 of a jack 7 and is cut between a fixed knife block 40 and a movable knife 20 advanced by a jack 41. A 46mm. film may be advanced from the opposite end of the block 3 in guide grooves 71, 76 by and between rollers 45, 46 rotated by a knob 51 to be cut between a fixed knife block 56 and a movable knife manually advanced by a handle 66. Cut film 180 is gripped in the end of the pivoted arm 42 carried by a shaft 85 which has one end formed as a pinion meshing with a rack 88, whereby operation of a jack 90 causes the rack 88 carried on the jack shaft 89 to rotate the arm 42 to carry the cut film 180 to overlie the lower shutter 158 of the mount 122 which rests on an apertured support 120. A reciprocating slide 130, driven by a jack 133 and mounted beneath the support 120, carries a blade spring 138 slidable beneath the support 120, carries a blade spring 138 slidable beneath the support 120 and a roller 135 mounted on a shaft 134 passing above the support 120 whereby actuation of the jack 133 causes the upper shutter 158 to be closed between the advancing roller 135 and blade spring 138 and then, by return of the slide 130, the closed mount 122 with the film 180 therein is moved forwardly to be picked up between the presser rollers 140, 142. Other arrangements of blade springs are described wherein the gripping action is enhanced. The operation of the various jacks is controlled in sequence by a manually operable valve lever 170 whereby compressed air from a pipe 165 is communicated through an opening 166, a transverse bore 167 and a passage 168 to various pipes, such as 8, 19, communicating the jacks 7, 41, 90, 133.
